[35.1] Is there a TeX or LaTeX macro that fixes the spacing on "C++"?

Yes, here are three (the first prevents line breaks between the C and "++"):

    \def\CC{{C\nolinebreak[4]\hspace{-.05em}\raisebox{.4ex}{\tiny\bf ++}}}
    
    \def\CC{C\raise.22ex\hbox{{\footnotesize +}}\raise.22ex\hbox{\footnotesize +}}
    
    \def\CC{{C\hspace{-.05em}\raisebox{.4ex}{\tiny\bf ++}}}

[35.2] Are there any pretty-printers that reformat C++ source code?

In alphabetical order:

• C++2LaTeX is a LaTeX pretty printer. It is available via ftp from ftp://ftp.germany.eu.net/pub/packages/TeX/support/pretty/C++2LaTeX-3.02.tar.gz
• C-Clearly by V Communications, Inc. is a Windows program that comes with standard formatting templates and also allows you to customize your own. http://www.v-com.com/
• GNU indent program may help. It's somewhere on ftp://www.cygnus.com [Note: If anyone has a better URL, please let me know (cline@parashift.com).]
• tgrind is a Unix based pretty printer. It usually comes with the public distribution of TeX and LaTeX in the directory "...tex82/contrib/van/tgrind". A more up-to-date version of tgrind by Jerry Leichter can be found on: ftp://venus.ycc.yale.edu/pub in [.TGRIND]. [Note: If anyone has an updated URL for tgrind, please let me know (cline@parashift.com).]

[35.3] Is there a C++-mode for GNU emacs? If so, where can I get it?

Yes, there is a C++-mode for GNU emacs.

The latest and greatest version of C++-mode (and C-mode) is implemented in the file cc-mode.el. It is an extension of Detlef and Clamen's version. A version is included with emacs. Newer version are available from the elisp archives.

[35.4] Where can I get OS-specific questions answered (e.g., BC++, DOS, Windows, etc)?

See one of the following:

• MS-DOS issues: comp.os.msdos.programmer
• MS-Windows issues: comp.windows.ms.programmer
• Unix issues: comp.unix.programmer
• Borland C++ issues (e.g., OWL, BC++ compiler bugs, general C++ concepts, windows programming):

[35.5] Why does my DOS C++ program says "Sorry: floating point code not linked"?

The compiler attempts to save space in the executable by not including the float-to-string format conversion routines unless they are necessary, but sometimes it guesses wrong, and gives you the above error message. You can fix this by (1) using <iostream.h> instead of <stdio.h>, or (2) by including the following function somewhere in your compilation (but don't call it!):

    static void dummyfloat(float *x) { float y; dummyfloat(&y); }

See FAQ on stream I/O for more reasons to use <iostream.h> vs. <stdio.h>.

[35.6] Why does my BC++ Windows app crash when I'm not running the BC45 IDE?

If you're using BC++ for a Windows app, and it works OK as long as you have the BC45 IDE running, but when the BC45 IDE is shut down you get an exception during the creation of a window, then add the following line of code to the InitMainWindow() member function of your application (YourApp::InitMainWindow()):

    EnableBWCC(TRUE);
